It's interesting noting that Kevin Greene was actually the Rams' reincarnated Youngblood. He burst on the scene (with very little fanfare) as an unknown LB-DL hybrid right after Youngblood retired and was mostly a backup playing on special teams and only seeing the field on defense in rare substitutions. Mirroring Jack's start back in 1971. Greene was just an average backup type in my eyes. A ho-hum okay great I don't know that you'll be back next year kind of player. I first really took notice of him in 1986 when he had a sack on SNF against the Cowboys. The next time I was aware of his impact was that strange strike shortened scrubs-in-play 1987 season when he jumped to block a Warren Moon swing pass and came up with an equally strange pick 6.
Then in 1988 watching him break out as a sack master put him on the map for good and I became a believer. That SNF game that same year he had one of the greatest games against Montana sacking him 4.5 times. They had FB Rathman blocking him and Green just powered by or jumped over his attempted blocks for the kill. After the whiner-stomping game (38-16 Rams) the story was revealed that during warmups Greene was obsessively calling out "I'm comin' to get you Joe!!!!" at Montana during warmups. 16 just looked at him strangely and said to himself, "okayyyy." And later the sacks poured in. Greene was like a giant swooping bird from an old Hitchcock movie.
For me it went Youngblood, Greene, Carter, nobody, Donald.
